Find slow queries in mongo DB

A few show tricks to find slow queries in mongodb

Enable profiling

First, you have to enable profiling

> db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...

A consul-template plugin to get EC2 metadata

ec2-consul-template-plugin

About

This is a simple little Python script to let you query EC2 metadata from consul-template. It's only requirement is boto. It uses the EC2 internal metadata service so it does not require any API keys or even a region. The only caveat is that this can only be run on a machine on EC2.

Usage

You can give no arguments for full dictionary output or one or more arguments to get specific key(s). Put it somewhere on your machine, chmod +x it and give the full path to consul-template.
